Run android service via remote command

I have the following code that runs in a service where it captures screenshots from Android. What technology could I use to send a remote command to this service to execute the task? I don't want it to run from a MainActivity button. Firebase cloud messaging ? Websocket ?

how to feed an image to TFLite pre-trained model in android using Java?

I am new to android development,
I need to get a pre-trained image classification model and run it with the image I choose,
I managed to choose images from the gallery and retrieve the image from URI beside loading the TFLite model
I also saw tutorials about TFLite model conversions and managed to run a simple model converting C degrees to F degrees
I can't do this with an image, any help?

Seems like you are trying to integrate an image classification model of mobilenet. Try the TFLite Task library, which will take 5 lines of code to run and it encapsulate image processing and output processing automatically for you. See the instruction and the Android app example.

Unable to fetch file from google drive

I am working on a project where user can upload a document to my server. This file can be selected either from local storage or a cloud storage ,say google drive. When i click on the file from file chooser all i am receiving is an account info and doc info as a uri, When i tried to fetch doc from this URI it is showing FileNotFound . I have gone through Drive API also but It is a bit confusing to me. Following are the points i came accross while trying Google Drive API:
1. How to select file from local storage.
2. How do I get FileId form the selected file.
I tried with the following code snippet:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.setType("**/");
startActivityForResult(intent, 1000);
and In onActivityResult
#Override
public void onActivityResult(int requestCode, int resultCode,
Intent resultData) {
// The ACTION_OPEN_DOCUMENT intent was sent with the request code
// READ_REQUEST_CODE. If the request code seen here doesn't match, it's the
// response to some other intent, and the code below shouldn't run at all.
if (requestCode == 1000 && resultCode == Activity.RESULT_OK) {
// The document selected by the user won't be returned in the intent.
// Instead, a URI to that document will be contained in the return intent
// provided to this method as a parameter.
// Pull that URI using resultData.getData().
Uri uri = null;
if (resultData != null) {
uri = resultData.getData();
Log.i("URI", "Uri: " + uri.toString());
try {
readTextFromUri(uri);
getMimeType(this,uri);
} catch (IOException e) {
e.printStackTrace();
}
// showImage(uri);
}
}
}
private String readTextFromUri(Uri uri) throws IOException {
// FileInputStream fileInputStream=new FileInputStream(uri.)
InputStream inputStream = getContentResolver().openInputStream(uri);
BufferedReader reader = new BufferedReader(new InputStreamReader(
inputStream));
StringBuilder stringBuilder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
// fileInputStream.close();
// parcelFileDescriptor.close();
return stringBuilder.toString();
}
Conclusion:
Can anyone please send me a link how to upload a document(I should even check the extension of the document) from both local storage and Google drive in a File chooser.

You can use VolleyPlus instead of Volley to add this feature.
jsonRequest.setOnProgressListener(new Response.ProgressListener() {
#Override
public void onProgress(long transferredBytes, long totalSize) {
int percentage = (int) ((transferredBytes / ((float) totalSize)) * 100);
}
});
There's a nice code snipplet how to do it here:
https://github.com/DWorkS/VolleyPlus/issues/53

why when i trying to upload image with size 1.5mb it's said error while uploading, but actually the image is successfully upload?

why when i trying to upload image with size 1.5 mb it's said error while uploading, but actually the image is successfully upload? and if i trying to upload with size 100 kb it's said Image Uploaded Successfully
